Even though Adobe seem to have started dumbing it down I'd still suggest Lightroom and outright purchase is probably still the way to go. LR has so many features now that it's actually getting quite complex but there's surely very little you can't do in it.
If you want Photoshop as well, it's probably best to get them (PS + LR) on subscription at about £100 p.a. but for many people it's probably overkill.
